Abstract :
In this paper, a Programmable Gain Amplifier (PGA) used for OOK UWB receiver is presented. It achieves a 100MHz bandwidth and a 19-40dB 8-step programmable gain. Furthermore, voltage-current DC feedback technique is adopted in order to realize DC offset cancellation (DCOC) at the output. This work is implemented in TSMC 0.18um CMOS process and consumes 1.26mW power.
